Q:

Oil is leaking 316796140 Craftsman Trimmer

A:

Thank you for your question. I am sorry you are having a problem with the Craftsman trimmer model 316796140. If the unit is leaking oil I recommend checking the oil level first. If the engine is over filled, the engine could leak oil out the crankcase breather. If the oil level is fine, check the O-ring on the fill plug. If the O-ring is cracked and not sealing the engine could leak out. If that O-ring is fine, I recommend wiping the engine down and try to determine where it is leaking from. Once you find the leak, inspect the bolts around where the leak is coming from. If the bolts are loose, it can cause the leak. If the bolts are fine, the seal where it is leaking needs to be replaced. The parts for the trimmer can be ordered from the following link. Replacement parts for a Craftsman trimmer model 316.796140.   If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears  technician.  Here is a link that will provide the nearest drop-off locations:  Sears Home Services.    I hope this is helpful. Please let me know if you need further assistance.  Mark

Q:

How do i install the piston into the cylinder with out a ring compressor and does the roll pin in the piston face a certain direction in the cylinder. Parts man

A:

To install the piston coat the walls of the cylinder with a light coat of 30 weight oil. Push the piston in until the bottom ring stops it. Squeeze the ring with your fingers while exerting slight downward pressure on the piston. Do this on each ring. You don't need a ring compressor for these small engines. You can squeeze the rings with your fingers as you install them.

If the piston has an arrow on the face, point the arrow toward the exhaust port.
